Some good news for coral reefs

Simon Donner (2009) and his colleagues have discovered that corals that have survived heat stress in the past may be more likely survive climate change in the future. Until recently, it was widely assumed that coral would die off worldwide as the oceans warm. The study suggests a roadmap on the impacts of ocean warming and will help communities identify locations where coral reefs are likely to adapt to climate change, the team says.

New survey method reveals more diversity on coral reefs

Nancy Knowlton

Using DNA barcoding for the first time to survey coral reefs, Nancy Knowlton (1999) and her colleagues have found much larger numbers of species living on coral reefs than previously estimated. Their findings suggest that the diversity of life on the world's coral reefs has been significantly under-detected by traditional surveys, which require more time and work to complete. As a quick, efficient method, DNA barcoding has "enormous potential for use in broad global surveys, allowing us to find out what is living in the ocean now, and to keep track of it in the future," Knowlton says.

Record year for Caribbean coral reef die-off?

Temperatures in the Caribbean this year broke 2005 levels, leading to fears that the coral reef die-off could also surpass 2005 levels, the worst year on record for both. Nancy Knowlton (1999) reported that she has never seen bleaching like this in Panama before. The reefs she studies are now covered in very rare layers of grey slime from dead microbes, a condition that she said is abnormal even for bleached reefs.
